Q:
What would your design or feature "wish list" be for this product?
25 answers
Answers:
A well designed machine made, moderately priced. Tees, Elbows, Connectors ETC in a good range of sizes, made from a high strength composite material such as Carbon fibre or glass fiber using O ring seals or high strength glued joints. Not necessarily flanged joints that are expensive to manufacture and require additional jointing materials etc.
~Ray W, Engineer, Sydney, Australia
I wish that a wide variety of assembly tools (holders, grippers, compression tools, etc.) were available for a given product line and that the products were designed to be easily and quickly implemented with those tools.
~J-dub, Research & Development, Seattle, WA
Light weight, corrosion resistant, and the ability to hold 6K psi worth of pressure across all sizes. O-ring face seal and bite type connections are probably the best for sealing.
~Jeff K, Marketing/Sales, Atlanta, MN
Product finish surface finish suitable for bio pharma use thread selection swivel ability on 90 degree fittings non shedding of chrome plating.
~P J O C, Engineering Consultant, Cork, Ireland
A push to connect that didn't pack full of road dust and dirt to become impossible to release the tube from.
~Rodger Trounson, Marketing/Sales, Invercargill, NewZealand
Better illumination output with less power (lumens/watt with good colour rendering properties)
~Shanmugasudaram Rengasamy, Maintenance manger, Coimbatore, India
Corrosion protection in base material not plating. Strength and durability. Affordable.
~Jon B, Faculty/Staff, CO
Compatibility with the different specs. Can AN, MS, etc be mixed with compatible AS?
~Dave C, Engineer, Stennis Space Center, MS
Low temperature and mechanical resistance to -60°c. Specially VCO O-rings.
~Trond G, Research & Development, Horten, Norway
Should not fail within its design pressure & temperature limits
~Naeemuddin A, Facilities Manager, Fujairah, UAE
More in lines with ease of connection and fluid compatibility.
~Timothy D, General Management, Brainerd, MN
Easily selectable fittings for both male & female connections.
~John R., Engineer, Fort Wayne, IN
A quicker and reliable system not using threads and ferrules
~Clive S, Production Engineer, Waterdown, Canada
They need to seal, readily available, decently priced
~Marketing/Sales, N. Royalton, OH
High pressure, weather resistant, lightweight.
~FRED O, Marketing/Sales, MIAMI,
More corrosion resistance to tube fittings
~Sampsa V, Technical Support, Jyväskylä, Finland
Metric threads on barb tail fittings
~Deon V, General Management, Gosford, NSW, Australia
True universal thread specification
~Robert Keller, Marketing/Sales, Suwanee, GA
Just a simpler selection process
~Engineering, Design, Rugby, United Kingdom
Simplified selection processes

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of tube fittings?
26 answers
Answers:
Choose tube and port connections that separate the sealing requirement from the mechanical holding requirement. Splitting up these two functions with different characteristics of the fitting design is to the end user's benefit. Using fittings with soft seal technology is better for long term leak prevention.
~Jeff K, Marketing/Sales, Atlanta, MN
When using taper threads on fittings use a thread sealant not teflon tape as it can leave small pieces in the lines to block valves and orifices etc. Don't over tighten fittings with taper threads into alloy valve bodies as it will crack the valve.
~Rodger Trounson, Marketing/Sales, Invercargill, NewZealand
Know your application specifications such as media, flow requirements, system pressures (max operating, impulse, working), port sizes, and any unique requirements. Only by knowing all these parameters can the tubing and fittings be recommended.
~Robert Keller, Marketing/Sales, Suwanee, GA
Buy 5 times as many parts than you think you'll need, because you are also buying parts for the engineers that are going to "borrow" from you because they are too incompetent to spec out anything early enough to deal with lead times.
~J-dub, Research & Development, Seattle, WA
When interchanging adapter model numbers from one manufacturer to another maker of fittings always check thread style, the interchange may require a reversing of thread style in the creation of the model number.
~Mike N, Inside sales, Houston, TX
I have seen stainless steel 'cheap, no-name' fittings ex far east, actually rusting in offshore service after a couple of months in service.
~Hilton L, Technical Support, Mossel Bay, South Africa
Know the differences between styles. Familiarize yourself with how to recognize and measure the key features like size and thread pitch.
~Jon B, Faculty/Staff, CO
I guess engrs (and mechanics/technicians) must learn the new AS designations as we move away from AN & MS designations
~Dave C, Engineer, Stennis Space Center, MS
Read manufacturers recommendations wrt tube preparation, cut lengths for correct insertion, proper swaging procedure.
~P J O C, Engineering Consultant, Cork, Ireland
Use manufacturer instructions for assembly, tightening torques etc. Use soft seal solution when possible
~Sampsa V, Technical Support, Jyväskylä, Finland
Make sure that the fitting that you're purchasing can handle the PSI that you're using.
~Steve K, Marketing/Sales, Auburn, MA
Selection per pressure, thread call out type of connection i.e. ORB, ORS, JIC etc
~Amay M, Application Engineer, Pune, India
Check the compatibility charts when selecting your materials of construction.
~Timothy D, General Management, Brainerd, MN
Common error people are doing in selecting the right specification.
~Naeemuddin A, Facilities Manager, Fujairah, UAE
Keep tubing to the minimum bend radius as specified by manufacturer
~Carl S, Marketing/Sales, Nashville, TN
Don't be afraid to get advice from others, regardless of who it is.
~John D, Product Manager - Hose & Fittings, Dandenong South, Australia
Go with name brand, too much is coming from China and failing!
~Micheal M, Senior Mechanical Engineer, Auburn hills, MI
Cut tube square, de-burr, do not over tighten nuts.
~Deon V, General Management, Gosford, NSW, Australia
Use tube suppliers gauges and tightening directions
~Clive S, Production Engineer, Waterdown, Canada
Not in the specific areas that we have discussed.
~Ray W, Engineer, Sydney, Australia
Be careful with checking the working pressure.
~Alcimar Freitas, Technical Support, Rio de Janeiro, Brazil
Match the material to the environment.
~FRED O, Marketing/Sales, MIAMI,
Check and re-check part compatibility
~Engineering, Design, Rugby, United Kingdom
Go for 28W T5 lamps instead of T8 40W
